Equinor will present six years of successful operating experience with boosting from the Åsgard and Gullfaks field at the Underwater Technology Conference. UTC Selected Topics will be held as a digital conference 18 November after lunch.

UTF and GCE Ocean Technology are happy to present 20 world-class presentation at UTC Selected Topics. One of the six themes is boosting technology and includes presentations from Equinor, OneSubsea and FastSubsea.

Boosting a Proven Technology

Subsea boosting is now considered proven technology based on Equinor’s governance and experience from Åsgard and Gullfaks. Caroline Harvengt, leading advisor subsea processing at Equinor will present the operational experience with subsea boosting.

Equinor reports that all four installed compressors have an impressive technical availability of close to 100%. The compressor trains at Åsgard are producing at full power and the production has been better than anticipated. Whereas the actual compressors have been working flawlessly, trips and upsets caused by other parts of the system have been seen.

As the reservoirs pressure continue to decrease, compressors with higher pressure ratio are being developed to mitigate the effect of the minimum flow rate in the production flowlines and to extend the lifetime of the Åsgard Field further.

The wet gas compressors at Gullfaks have been used to maximize value creation, adjusting oil/gas mix according to demand/price and processing capacity at the host. The compressors have been producing in different modes since start-up, at first in single mode, then in parallel mode, comprising of over 40.000 running hours.

Equinor reports that projects and operators are taking onboard the technology and that the industry is ready for multi-use implementation. Compressors adjustments for unmanned topside application are also being assessed.

Subsea Boosting Saving 75% Energy

Subsea boosting can offer remarkable energy and CO2 savings per unit produced oil and gas, compared with conventional lifting methods. The associated benefit of improved production should be well known.

Ina Ekeberg, technical sales manager at OneSubsea, presents that 75% of the energy consumed for producing oil or gas can be saved by applying subsea boosting pumps or compressors. Based on this, subsea boosting can save energy equivalent to the consumption of 20 000 households in one single application.

Field of the Future and Low Carbon

UTC Selected Topics will also feature dedicated session on Field of the future, All-electric, SURF/operations, Digitalisation and Low carbon/technology transfer.

There will be presentations from Equinor, Aker BP, Total, BP, OneSubsea, Subsea 7, Baker Hughes, Aker Solutions, DNV GL and many more.

We will have a live Q&A feature for you to submit questions to the presenters during the event. The event will have three parallel sessions making it a compact event possible for most of the subsea world to follow the event online between 13:30-17:00 CET 18 November.
